well, we did the initial tune on my widebody, and the results are pretty good, basicly flat torque, over 300ft lbs from 4700 rpm to redline. I'll post a couple differnt graphs, because none have all the feature you'll want to see together, but the car goes to the top of third on the street in less than 5 seconds, and hits 60mph in under 3 seconds(stopwatch/terrified passenger). This is babying the clutch, as it hold fine once under way, but would disintegrate if I dump it at more than 3500rpm in first. There is no tire spin, so the widebody is paying off. We will be working on making the torque earlier, but for now the car is scary fast anyway. here are a couple graphs, basicly 506/387@25psi, and 449/331@20 psi(which is what I will run on the track to start). No cooling issues with 35 back to back pulls(3 hours) on the dyno on a 90* day with one small fan.

I just tried to scan these in, and they are too large, I guess for now(until I learn to use my scanner, I will photograph the sheet. They are all SAE with no smoothing. Now, I am moving on too getting the suspension dialed, we will be aligning, and corner weighting tomorrow, followed by some more cooling mods, and brake work. The car will hit the track for the first time 8/6-7 at Infineon. I hope to put the car in the hands of some semi pro drivers, to help me get it dialed in. That's it for now, til i photograph the dynos, and get the car on the track. Carl

 

Holy ****!!!!

PICS!!!!!!

 

Let me be the second to say:

Holy CHIT!

 

Here's a link to three sheets. Watch the scaling, I added some approx RPMs by overlaying some graphs, but you get the idea. If you have not seen my car, there are pics as well. I met with Tripoint at ALMS over the weekend, and we may be making some custom strut housings for the front to allow 16x12 w 24.5x12x16 slicks (or bigger) in the front of the car, we are already running the 13" slicks in the back. Rates are 600/400 to start, but we may go alittle softer til I get used to the car. The car feels like its hitting a wall at ~80-100, I am hoping that is my Aero kicking in, and not something wierd in 4th gear. seem likely it's the aero, since with this much power, it should just pull like crazy through 150mph Anyone know what 5th at ~7500rpm equates to in speed in a TII? Carl

timing is a 6 degree split with 17* advance@25psi. AFRs are mid 11s on 111 octane with 6725-11.5 plugs. I will share any info on this car, no secrets, just lots of fun

 

What class are u racing it in? SCCA, NASA.. cuz i'm looking into building a car alot like yours in the next few years and wanna know where i can race it. Thanks alot man. Your car rocks.

 

Basicly it's NASA Super Unlimited, I could run it in SCCA SPO, but it really would get killed there by out of date Trans Am cars. You might be able to get it into ITE, but it's a little over the top for that class. I built this car because I wanted to, it is at the bottom of any class it legitimately fits in, and stupid fast for everything else. It is a crazy HPDE/SU car built to have fun, and be exactly what I want it to be without regard for where it fits. If it was a Porsche it would have a home, but nobody else builds cars like this, so it really has no home. If you want regular wheel to wheel racing at this level, look for an out of date world Challenge car, and drop ~30-50K. I did this a grand at a time over almost two years, I did not have the money to buy a car with this level of performance all at once. Coming from ~600hp daily driver, it's hard to find a race car that can satisfy... Anyway, If you want to go really fast, and do not care about having real competition on a day in, day out basis, this sort of car is for you. If you want wheel to wheel with reasonably matched cars, look somewhere else. ****, you could AX it in STX, with 335-30 out back, and 315s up front, but why??? Later, Carl

 

looks good carl, I have some questions for you about the cage and wheel tire combos. Send me a pm and we'll talk.

congrats again, impressive numbers.

 

What should the PM say? You can reach me at 707-696-2705. Cage is Kirk, wheels are real racing 16x12(6 " backspace)/16x11 (6" backspace, .5" spacer) I am going to move the strut inboard, initially by making the hole at the top oval, and using a slightly smaller bolt, but I am working on a custom strut housing to move it all inboard by ~1/2". Slicks are goodyear Bias Ply take-offs. Carl

 

?????

The stock car isn't even STX legal.

Maybe FP, but I don't think so. It would be right up in the classes. Even modified classes may not fit.

 

I'll give you a call this evening

 

It would be BP, and what puts it out of BP? All the suspension points are original, It has less lightening than most any Prepared class car. The motor is correct. It was delivered with forced induction, what's the rub? It's far less modified than Tripoints FP car, just makes a **** load more power. As for STX, I was just throwing that out there, you might need to change a thing or two, or the cage might be a problem, but Really it would be a BP car, and as I mentioned it would have to loose about 300lbs to compete. Does STX preclude cages? The cage is not gusseted(yet), is engine management limited? If not, then only wheel width might be a problem, in which case I'd just downsize a little, that would help heat the tires anyway. Sooo, like I said, I built it for me, just because it makes more HP than most does not preclude it, as ther are no HP limits. The AP corvettes make 600hp, and weigh 2100lbs, not to mention the same width, or wider tires than me. The FC in BP is potent car, With the right driver it is a contender, winning FP, and BP quite a few times. Anyway, there are two approaches, build your dream, and run it where they will let you(my approach), or build a car to spec, look like everyone elses, but have close wheel to wheel racing. Who knows, I may decide to try and get it into ITE, that is a tough group, they turn ~1:45 at Infineon, that's not far off the world challenge car pace. I have already listened to the Pro7/ITS etc contingent, and their contention that it's all about the car, and not the driver, whatever, the more car, the more driver it takes to go fast, ever try and drive a highly tweaked race car, it's so nervous, it takes some serious driving to keep it on the track. Live and let live, to each his own, and for me, thats one crazy FC

 

I was talking about autocrossing specifically. STX requires a 4 seat car. A 2+2 is not allowed. STS2 is the only street touring class the car may have fit in. It is really pretty strict though. My CSP legal GSL-SE is not legal in STS2 due to the clutch type LSD. Your car is way outside the street touring rules.

With the cage, interior, widened body, rear wing, and various other things it would automatically jump to "F" Prepared. There may however be some mechanical things done that are still not legal in that class. The road racing classes do not cross over to autocrossing. FP for me is not the same as FP for a club racer.

Well, I just took a look at the rule book. You are right the turbo goes to "B" Prepared. I guess what I said still stands though.

I just thought I would help clarify this stuff for anyone that may be reading and thinking about building a monster FC for autocrossing. I was not commenting on your car. It is spectacular.

It can't be said any better than that.

 

Carl- Nice numbers... what is your redline and what tune do you plan to race it with?

Your plan is to run at Infineon on August 6th-7th right?

The LG Motorsports Corvette turned a 1:39 at Infineon this weekend in the ALMS series. That is cooking.

 

If we run the long course... we will probably run the shorter hairpin at 7..... knock 2 ish seconds off..


Marcus

 

For THAT reason Carl.. (And a VERY nice FC) I will ALWAYS have respect for your car.
You built it for YOU.

I wish everyone in the racing world would get OVER the goddamn It has to fit a class thing. If it has a plate it ISNT a "real" race car.

You are right though about the SPO thing. /shudder
One of the times in the last year I was at Sebring with the F500 Team I help out with, there was a SPO? Supra. Yes it was Every 16 year old's wet dream. I mean it was MEAN as hell. Fast and Ricey all the way. Fender flares.. Hood.. Wing.. Seat.. Cage.. Sillllly Japanese shocks etc.. Everything a 150K could buy you from Japanese tuner mags. This thing was an AMAZING animal. HUGE turbo.. HUGE intercooler.. HUGE Radiator.. HUGE brakes.. Sequential Tranny.. it had "It all"

Or it appeared to..

Well.. Come the ground pounder race... Well...... lets just say.. he wasnt up front.
The couple GT1 C5R corvettes.. TOTALLY checked out on this thing. You all know.. the Yellow ones? The Pretty Yellow ones.. that GM built? Yep thats them.
Then there was the 80s GT1 Camaro that was chasing them... and the other later model Camaros.... All GT1.. a couple SPO. Yep.. alllllllll Checked out.
The thing sounded like a 100 Gallon air tank with a BAD leak. All WOOOOOOOOOSH out of the carousel. Amazing to watch.. THis thing was DIGGING out of the corners.....
But not as much as the others.
ANd it didnt go around the corners as fast either.
And it didnt stop as well either...

Pure bred Race car chassis.. with a Rat motor tuned to the limits VS a REALLY badass Street based car.
Pure Tube chassis racer usually will check out.

Granted... last weekend there were a couple GT1 camaros I kept catching and passing in my ITA 1st gen.... but Hey.. they had problems.. and were new. There was a "Bush" car there too with a 800hp SB2 engine in SPO. He had no problem with the GT1s.

Glad to see you are getting her together Carl.. and look forward to seeing some Video or Pics of that beastie on the track.
Nice Ride.

 

Any pics of your fuel cell setup? I remember you were looking around for a ideas a while back.

 

those are the Pratt and Miller cars. they're amazing and too good to be considered a corvette.

 

I'll run it at 20psi~450rwhp, 6-7 is booked, but I am working on it, most likely I will be there. Car is alot heaveier than I thought, 400lbs heavier, but that will all go soon enough. So Power to weight is not what I thought for now. All the work I did on the car added weight, now time to put it on a diet. Car weighted out within 5lbs on the cross weights, the car is pretty light in the right rear. Carl

 

Nice ride, Carl! Dial it in good and keep it shiny side up!

 

Yes, I will post in the next week or so, stock location, even stock straps. Surge, etc. Carl

 

I hope toi be at Infineon 8/6-7, anyone else? Mark, LMK about your Sunday spot, I am interested, but I do not know how much time you get TT'ing. Carl

 

I'll be there, hanging out. I'll swing by your pit spot.

Marcus

 

Carl, I have to forfiet the entire weekend as I need the irons from my spare engine for the new 1/2 bridge being built up. I'm cancelling tommoorow or Tuesday but the deadline for refunds is not until Friday. Not sure if I can just give you my spot as it is not up to me. Call me and maybe we can figure something out.
